Application filed August 16, 1906. Serial No. 330.790.

To all whom it Hila y concern:

.Be'.1t,known that I, ENOGII H. MAJOR, a

citizen ofitheUnitedStates, and a resident of Hampshire, haveinvented an Improvement following-description, in connection with the accompanying. drawing, is a specification, hketletter's on the drawing representing like P 1 1.

This invention relates to shuttle-motions for looms 'wherebythe shuttle is reciprocated back: andfforth. through the shed, and more particularly to: tiicpieker-stibk and adjacent parts; and it has for its obj ectthe production of novel means for sustaining the lug-strap on therpickerst-ick without the use of bolts or other fastening: devices extended into or through"thesticki i The various novel features of my invention will be fully described in the subjoined specification, taken in connection with the accompanying drawing and particularly pointed Figure 1 isa front elevation of the lower end of a picker-stick, its attached shoe, and the support or stand on which the shoe rocks, 'illu'stratingone embodiment of my present invention, 'the iiovel means for retaining the lug strap in place being very clearly shown. Fig. 2 is atop lan'v'iew of thepartsshown in Fig. 1 below t e lii1ef22. Fig. 3 is'a side elevation of the mechanism shown in Fig. 1 lookingtowardthexright. p

The support or stand 1 having an offset hub 2 to receive thefl'ay rocker-shaft A, Figs. 1 and2, to" which the stand is rigidly secured, as by a set-jscreugB, has its outer end upturned at 4 to act as a stop and limit outward' movement of the shoe, and side lugs 5 are ar ranged on the stand'to cooperate with projections on the shoe, to be described, to limitinward movement of the shoe. An upright at 7 Fig. 1, to receive a shouldered stud 8,

clamped in desired position on the ear.

j'ccts transversely across the inner end of the stand and forms the fulcrum for a checking member (shd'wn as a lever 10) extended above the stand and having depending guldes 11 to loosely embrace it and prevent lateral i displacement ofthe lever. A spring 12, seated on the member 10 near its fulcrum 8, is held in place and also adjusted as to tension by a headed bolt 13, the shank of which is passed through the spring and a hole in the member 10 and then through a slot 14 in the stand, a nut 15 onthe bolt bearing against the bottom of'the stand and regulating the spring tension. It will be manifest from Fig.

1 that the spring depresses the free or outer end of the checkmg member, and the slot 14 permits movement of the bolt 13 when the fulcrum-stud S'is adjusted on the ear 6 without interfering with the operation of the spring.

The checking member or lever 10 is out out at 16, Fig. 2, to receive the toe 17 of the shoe 18, the curved sole of which rests and rocks upon the flat top of the stand in usual manner. The shoe is upturned at" 19 to form a. species of upright seat to receivethe lower end of the picker-stick P, the bottom of the stick resting on the shoe at the heel, which is shaped to form a guide-stop 20 for the stick. The seat forms also onemember of a clamp, the cooperating and relatively movable member being shown as a plate 21, having side ribs 2 to embrace the front and rear faces of the stick. The member 19 has hollow bosses 19'' to support bolts 23, which pass loosely through hollow bosses 21 on the other clamp member 21, nuts 24: when set up on the outer 7 ends of the bolts drawing the clamp members together and rigidly and securely clamping the stick on the shoe.

The combined clamp member and seat 19 forms a supporting-housing in which a large part of the picker-stick is securely held and prevented from lateral movement, and the movable member 21 whensetup completes the attachment to the shoe, so that without bolts or other devices passing through or into the stick the latter is rigidly and yet detach ably connected with the shoe. By obviating the necessity for holes or openings in they picker-stick it is less liable to cracking and breakage under the heavy strains to which it is subjected when in use.

The top of the toe 17 of the shoe is concaved at 25 to form a cam-surface with which the free end of the checking member or lever 10 cooperates. When the shuttle engages the picker-stick and throws it outward, the toe rises and the end of the member 10 wipes crum-stud 8 in the ear 6 the c over the cam surface 25, the said member bemg rocked on 1ts fulcrum 8 against the spring" 12, and the'force of the spring is thereby applied to check in a gradual manner the outicker-"stick and ward; movement ot the through it the movement 0 the shuttle. By

adjusting the nut'15 the tension of the check-' in'g-spring is varied, and by adilusting'the fuleckihg action as a whole is regulated, for by moving the stud to the right, Fig. 1, the checking meniher 10 engages the cam-surface farther from the picker-stick and the checking action is increased, and vice versa. -Depending fingers "26 011 the shoe embrace thestand, preventing lateral movement-of the shoe thereon,'an'd by cooperation with the lugs 5 the fingers limit any bodily inward movement of the shoeupon the'stand.

I have herein provided a novel, simple, and eflicient lug-strap "holder which is held in operative position on the picker-stick by friction, and herein the clamping device'which' connects the stick and the shoe is utilized to retain the lug-strap holder in osition. I prefer to make the holder of a piece of sheet 'metal in strap form bentto form a loop 27 and an elongated extension or shank 28,

there y with the loopat the desired height to receive the lug-strap L,=.Eig. 1. By loosening the clamp the shank'can be moved up or down to pro erly position the loop 27, after which the c amping-nuts 24 are set up, the clamp serving to hold the icker-stick on the shoe and the lug-strap hol er on the stick. I thereby obviate the necessity of perforating, nicking, or otherwise weakening the stick in order to secure and adjust the lug-strap holder. The resiliency of the shank permite of slight movement of the loop toward andfrom the picker-stick, while at the same time serving to cushion such movement, and thereby prevent undue wear.

My invention is not restricted to the precise construction and arrangement of parts herein shown and described, as the same may be modified or changed in various details by those skilled in the art without departing from the spirit and scope of my invention.

The

Having fully described my invention, what detachably and rigidly connect the stick and shoe, and a lug-strap holder operatively held 6b by the clamp.

2. A picker-stick, a lug-strap holder havmg a strap-receiving loop and a resilient, elongated shank, and means to frictionally engage and clamp the latter on the picker- 6 stick.

I 3. A picker-stick, a loop-like lug-strap holder having a thin flat shank adapted to bear against the edge of. the stick, and a clam to frictionally engageand retain the '70 frictional engagement.

5. A picker-stick, a' lug-strap holder having an elongated depending and flat-shank, and a friction-clamp to adjustably clamp the lower end of the shank upon the picker-stick, the

shank being interposed between the clamp 8 and the picker-stick.

6. A lug-strap holder for picker-sticks, composed of sheet metal bent to resent at one end a strap-receiving loop and aving an elongated shank, and means to clamp the extremity of the shank upon the pickerstick.

7. A resilient sheet-metal lug-strap holder having a strap-engaging portion and an elongated flat extension adapted to rest against 0 the edge of and be fixedly clamped upon the picker-stick, and means to clamp the extremity of the shank thereupon. v

8. A icker-stick, a shoe-therefor having an uprig t seat to receive the end of the stick, 5

and constituting one member of a clamp, a cooperating; relatively movable member to bear against the stick, a lug-strap holder held in adjusted position by the relatively movable clamp member, and means to compress oe the clamp members upon the stick.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
